javascript - Not able to append options to select -

-

I'm not sure why this works, but when I pass in numbers 

  & lt; Form ID = "Form 1" Runat = "Server" & gt; & Lt; Div id = "facebook photo-iframe content" & gt; & Lt; Div & gt; & Lt; P & gt; Sign in & lt; / P & gt; & Lt; P id = "LoginButtonContainer" & gt; Input  & Lt; / P & gt; & Lt; P & gt; & Lt; Select ID = "facebookAlbumDropdown" /> & Lt; / P & gt; & Lt; Div id = "facebook photocontainer" /> & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Form & gt;  

  AddDropdownItem ("- test a few - select", "-1", "testDropdown"); Function AddDropdownItem (sText, sValue, sDropdownID) {$ ("#" + sDropdownID) .append ("& lt; Option Value =" + sValue + "& gt;" + steext + "& lt; / Options & gt;) ;}

This works

but it is not: 

  var id = 104388426283811; AddDropdownItem ("- some Select the test- "id.toString ()," testDropdown ");

What is the default option appears, but then when it tries to add another option So he creates a bomb with no errors which I can see in the firebug console and then the end The list is empty (no choice) when my code is to be run.

In the original Question based on the comment thread, this is my sample page that includes your argument (with a button wiring to add options for selection): 

  & lt; Html xmlns = "http://www.w3.org/1999/xhtml">  gt; meta http-equiv = "content-type" content = "text / html; Charset = UTF-8 "/> gt; Title & gt; jQuery test & lt; / title & gt; script type =" text / javascript "src =" http://code.jquery.com /jquery-1.4.2.min.js ">

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
